Alternating Current question

2023 · 1 Feb · Shift 2 · Q65

JEE MainPhysicsAlternating CurrentNumerical+4 / −1
A square shaped coil of area 70 cm270 \mathrm{~cm}^{2}70 cm2 having 600 turns rotates in a magnetic field of 0.4 wbm−20.4 ~\mathrm{wbm}^{-2}0.4 wbm−2, about an axis which is parallel to one of the side of the coil and perpendicular to the direction of field. If the coil completes 500 revolution in a minute, the instantaneous emf when the plane of the coil is inclined at 60∘60^{\circ}60∘ with the field, will be ‾\underline{\hspace{2cm}}​ V. (Take π=227\pi=\frac{22}{7}π=722​)
